Logicore 802.16e CTC decoder v4.0 - 1 SISO does not work if you put 2400, 24, and 2400 blocks into the decoder. How can I work around this?

Description

ForLogicore 802.16e CTC decoder v4.0,when CTC decoder is configured withone SISO, and if you send 2400, 24, and 2400 coded blocks to the CTC decoder, you will not see the output of third block(2400). How can I work around this?

Solution

Switching between the two sets is causing the problem.When the number of SISOs is equal to one, the two sets should be treated as one set. A workaround is to flush the decoder before switching between the two sets, or set the number of SISOs to greater than one.
